Application ledfkpril 11, 1921. `Serial No. 460,442.

consists in the novel construction hereinafter i disclosed.

An object ofthe invention isitoy provide` in a motor vehicle a pair of head lights sup ported and controlled so that they areindependently operable incident. tothe change of direction of the motor vehicle.

Additional advantages and novel feai'` tures of the construction will.A be ,apparent from the following detailed description thereof, taken in connection with theJ accompanying drawing, in which Fig. 1 is ay plan view of the operating mechanism for the lamps shown in association with the co-operating parts of the motor vehicle.

Fig. 2 is a front elevation showing the embodiment of the invention.

As illustrated in the drawing, the motor vehicle is provided with lamp supports positioned at each side of the vehicle, each ci said supports comprising a frame 1 conveniently attached to the fenders and extending intermediate the inner surface of the fenders 2. and the radiator 3 of the vehicle. Each of the supports for the lamps is made in separable sections so that the lamps et,

which are provided with short studs 5 and downwardly extending stems 6, may be pivotally mounted in the support. ln order to impart rigidity to the lamp supports a cross rod 7 extending between the supports may be provided. The stems 6 of the lamps extend downwardly to a point just beneath the front axle 8 of the vehicle. To the lower end of each of the stems is attached a lever 9, said lever extending in the 'longitudinal direction of the vehicle but substantially at right angles to the axle.

The front wheels 10, as is usual in motor vehicle construction, are supported on stud shafts 11 which' are a part of the steering knuckle 12 mounted at the ends of the front axle. The steering knuckle arms 13 extend rearwardly from the steering knuckles and are connected by the cross bar 14's.

The mechanism foroperating the lamps independently of each other is connected with the steering mechanism of the automobile. Asishown, `a rod 15fis pivoted to the rear rend ofeach of the levers 9 for universal pivotal movement. Each of the rods 15 extend inwardly for cooperation withian associated rod 1G. rlhe innerend of each ofthe rods 15 supports a dash pot cylinder 17. rilhe inner ends of the rods 1G arepivotedr for universal.movement, that is for movement in 'any direction, to a bracket or clevis 1S attached to the connecting rods 111. The outer end of each of the rods16 extends into the adjacent dash pot cylinder 17y and has a. pis

ton 19 thereon in the dash pot. A spring Q9.

encircles each rod 16 within the dashl'iot, the inner end of the spring bearing against the inner end of the dash pot and'thepouter end of the spring bearing against the piston 19.

A strong springQO of the retractile type is connected to the forward endof each of the levers 9, the innerends of saidsprings 20 ibei ing connected to an attachment 21 on the axle 8. Itfwill beobserved (Fig. 1) that when the automobile is travelling straight ahead, the pistons 19 are aconsiderable distance from the outer ends of the cylinders 17. If the automobile be turned, the inside lamp will be turned with the steering mechanism due to the fact that the piston 19 controlling theF inside lamp exerts pressure against the spring 22 suiicient to overcome the power of the spring 20. At the same time the outside lamp is left in its original position dueto the fact that the piston 19 controlling the outside lamp is free to move in the cylinder 17 toward the outer end of said cylinder. The pivotal connection between the inner ends of the rods 16 and the bracket 18 may be of any well known connec` tion permitting free vswinging movement of the rods 16 in any direction.

In the operation of the steering mechanism the movement of the cross bar 14 is in a direction opposite to the direction of turn of the vehicle. Thus, as the vehicle is turned, the lever 9 on the side of the vehicle in the direction of the turn is operated by a pull on the flexible link connection, thereby turning the lamp on the side in the direction of the turn to follow the path of the vehicle; while the lamp on the other side remains stationary dueto the fact that there is a lost motion iii the dash pot of the flexible link connection on that side of the vehicle. ln order that there may be no jerk or sudden movement of llO the lainp'it will be noted that springs 22 are provided in the dash pot intermediate the piston and the head ot the dash pot cylinder. When the steering mechanism is brought to `a straight away direction the springs 20 serve to restore the lamps to normal position. F rom the :foregoing description of the construction it will be apparent that it ac,

complishes a very desirable function in that it preserves the adjustment of one of the lamps straight to the front, while the other lamp is turned to light the path of the changed direction of the vehicle thus illumi-` nating a wide arca at the point of turn of the vehicle. u

I am aware that the invention may be modilied in certain iriarticnlai's without de` parting from the spirit and scope thereo'l". 'What I claim and desire to secure by Letters Patent is:- v

l. In a motor vehicle having a steering mechanism and lamps, the combination of a .stem for turning each of said lamps relative to the other, a lever attached to the lcwer end of each stem, a pair of rods having their outer ends pivoted to the rear ends ot' said levers respectively, a cylinder on the inner end of each of said rods, a second pail-cof` rods having their inner ends pivoted tothe steering mechanism and having their vouter f endsiextending into said cylinders respecspring connected to each of said levers for 40 actuating the springto restore the lamps to position to throw light straight ahead after the vehicle has completed its turn.

2. In a motor vehicle having lamps and steering mechanism, a `stem for turning the lamps respectively, to light the path oit'the changed direction oi4I the vehicle, a lever in connection with each of* said'steins, a rod pivoted to the rear end oiE each oi" said levers,

a pair of rods pivoted to the steering mecha-y msm for cooperation with the rods that'are pivoted to the levers, a dash pot device connecting' the rod that is pivoted t0 each lever` with the cooperating rod that ispivoted'to the steering mechanism arranged to turn the inside lamp as an incident to the turning ot the vehicle, and to leave the outside lamp undisturbed, andV means for restoring the lamp to its initial position after the vehiclehas completed its turn.
